libgsh 

This is a SDK library for building server applications that interact seamlessly with the gsh client. It provides essential tools and abstractions to enable efficient communication between the server and the gsh graphical shell client application.

Features

• Server-Client Communication: Simplifies the process of establishing and managing connections with the gsh client.
• Data Serialization: Includes utilities for encoding and decoding data exchanged between the server and client.
• Extensibility: Designed to be modular and extensible, allowing developers to build custom server-side functionality.

This library is an integral part of the gsh ecosystem, enabling developers to create robust and interactive server applications that leverage the graphical capabilities of the gsh client.

Build a Server

Do you want to build your own service with gsh? Choose between these out-of-the-box server implementations:

Recommendation
The async server provides better performance and scalability for most applications.

View the examples directory for service implementations using the async and simple servers. There you can view how they interact with the gsh client. View the compatibility document for more information on supported versions.

Architecture

The libgsh library is designed to be modular and extensible, allowing developers to build custom server-side functionality. It provides a set of abstractions and utilities that simplify the process of establishing and managing connections with the gsh client.
